Definitions
- This invention relates generally to techniques for handling information in an electronic network, and relates more particularly to a methodology for performing caching procedures in an electronic network.
- enhanced device capability to perform various advanced network operations may provide additional benefits to a system user, but may also place increased demands on the control and management of various communication mechanisms.
- an enhanced electronic network device that effectively handles digital image data may frequently benefit from an efficient implementation because of the large amount and complexity of the digital data involved.
- a methodology for effectively performing caching procedures in an electronic network is disclosed.
- a user device may communicate to selected buddy devices through a server in the electronic network.
- a messaging application of the user device may manage the offline caching procedure to locally store a cached message whenever the user device is unable to successfully transmit messaging communications over the electronic network due to various network conditions such as the server or the electronic network being temporarily inoperable.
- the messaging application may initially allow a device user to log-in to the server of the electronic network by providing various types of log-in information. The messaging application may then determine whether the server is inoperable by utilizing any appropriate means. If the messaging application determines that the server is inoperable, then the device user may determine whether to enter an offline log-in mode to thereby create and store a cached message for subsequent transmission to a selected buddy device in the electronic network. If the device user decides to log-in offline, then the device user may verify the log-in information previously entered, and may also correct any errors in the log-in information.
- the messaging application may then create a new cache file for the cached message in a cache that is part of a local memory resource of the user device, and may also store the foregoing log-in information into the cache file as part of the corresponding cached message.
- the device user may then utilize the messaging application to create and store any other appropriate message information corresponding to the cached message into the corresponding cache file.
- the foregoing message information may include, but is not limited to, a target destination identifier that specifies a particular buddy device in the electronic network, and may also include text message data which comprises the actual communication to be conveyed to the selected buddy device.
- the messaging application may then monitor the status of the electronic network to automatically determine whether the server has become available to receive the cached message by utilizing any effective means. If the server becomes available, then the messaging application may automatically log-in to the server by utilizing the previously stored log-in information. The messaging application may then automatically retrieve and transmit the cached message to the designated buddy device through the server and the electronic network. Finally, the messaging application may automatically log-off from the server, and may also purge the cached message that was previously transmitted to the server in order to conserve memory resources in the user device.
- the messaging application may temporarily store a video message to a designated cache whenever the user device is unable to currently transmit the video message to a selected buddy due to various network conditions such as the selected buddy device being offline, or being inoperable for other reasons.
- the cache may typically be implemented as part of the server, or may be a memory resource elsewhere in the electronic network.
- the messaging application may access a buddy list that may include various types of information regarding each of the buddy devices on the buddy list, including an on-line/off-line status indicator that displays whether each of the buddy devices is currently logged-in to the server.
- the device user may then utilize the messaging application to select a messaging buddy from among the listed buddy devices on the buddy list.
- the device user may utilize the messaging application to determine whether the selected messaging buddy is available to receive a video message from the user device by using any appropriate means. For example, the device user may simply view the foregoing on-line/off-line status indicators from the buddy list. If the selected messaging buddy is not currently available to receive a video message from the user device, then the device user may utilize the messaging application to create a new cache file in the cache to temporarily store the video message.
- the messaging application may also store various types of auxiliary message information into the cache file as part of the corresponding cached video message.
- the foregoing auxiliary message information may include, but is not limited to, a video format for the video message and a storage location identifier for the video message.
- the device user may then utilize the messaging application to create and store the actual video message data into the corresponding cache file, and may log-off of the server when finished.
- the selected messaging buddy may utilize a corresponding buddy device to log-in to the server by providing various types of log-in information.
- the server may responsively send a message notification to the buddy device regarding the cached video message that has been saved into the cache by the user device.
- the foregoing message notification may include any previously-stored auxiliary message information including, but not limited to, a video format and a storage location identifier for the cached video message.
- the selected messaging buddy may then download the cached video message from the cache, and may subsequently view the downloaded video message on a display of the buddy device. After initially viewing the downloaded video message, the selected messaging buddy may determine whether to retain or delete the downloaded video message after it has been viewed, and may then finally instruct the buddy device to log-off of the server.
- the present invention therefore provides an improved methodology for performing caching procedures in an electronic network.

Abstract
Description
- 1. Field of the Invention
- This invention relates generally to techniques for handling information in an electronic network, and relates more particularly to a methodology for performing caching procedures in an electronic network.
- 2. Description of the Background Art
- Implementing effective methods for handling information in an electronic network is a significant consideration for designers and manufacturers of contemporary electronic devices. However, effectively handling information utilized by devices in an electronic network may create substantial challenges for system designers. For example, enhanced demands for increased device functionality and performance may require more system processing power and require additional software resources. An increase in processing or software requirements may also result in a corresponding detrimental economic impact due to increased production costs and operational inefficiencies.
- Furthermore, enhanced device capability to perform various advanced network operations may provide additional benefits to a system user, but may also place increased demands on the control and management of various communication mechanisms. For example, an enhanced electronic network device that effectively handles digital image data may frequently benefit from an efficient implementation because of the large amount and complexity of the digital data involved.
- Due to growing demands on system resources and substantially increasing data magnitudes, it is apparent that developing new techniques for handling information in an electronic network is a matter of concern for related electronic technologies. Therefore, for all the foregoing reasons, developing effective systems for handling information in an electronic network remains a significant consideration for designers, manufacturers, and users of contemporary electronic systems.
- In accordance with the present invention, a methodology for effectively performing caching procedures in an electronic network is disclosed. In one embodiment of an offline caching procedure, a user device may communicate to selected buddy devices through a server in the electronic network. A messaging application of the user device may manage the offline caching procedure to locally store a cached message whenever the user device is unable to successfully transmit messaging communications over the electronic network due to various network conditions such as the server or the electronic network being temporarily inoperable.
- In practice, the messaging application may initially allow a device user to log-in to the server of the electronic network by providing various types of log-in information. The messaging application may then determine whether the server is inoperable by utilizing any appropriate means. If the messaging application determines that the server is inoperable, then the device user may determine whether to enter an offline log-in mode to thereby create and store a cached message for subsequent transmission to a selected buddy device in the electronic network. If the device user decides to log-in offline, then the device user may verify the log-in information previously entered, and may also correct any errors in the log-in information.
- The messaging application may then create a new cache file for the cached message in a cache that is part of a local memory resource of the user device, and may also store the foregoing log-in information into the cache file as part of the corresponding cached message. The device user may then utilize the messaging application to create and store any other appropriate message information corresponding to the cached message into the corresponding cache file. For example, the foregoing message information may include, but is not limited to, a target destination identifier that specifies a particular buddy device in the electronic network, and may also include text message data which comprises the actual communication to be conveyed to the selected buddy device.
- The messaging application may then monitor the status of the electronic network to automatically determine whether the server has become available to receive the cached message by utilizing any effective means. If the server becomes available, then the messaging application may automatically log-in to the server by utilizing the previously stored log-in information. The messaging application may then automatically retrieve and transmit the cached message to the designated buddy device through the server and the electronic network. Finally, the messaging application may automatically log-off from the server, and may also purge the cached message that was previously transmitted to the server in order to conserve memory resources in the user device.
- In one embodiment of a video message caching procedure, the messaging application may temporarily store a video message to a designated cache whenever the user device is unable to currently transmit the video message to a selected buddy due to various network conditions such as the selected buddy device being offline, or being inoperable for other reasons. In the foregoing video message caching procedure, the cache may typically be implemented as part of the server, or may be a memory resource elsewhere in the electronic network.
- In practice, after the device user of the user device has successfully logged-in to the server, then the messaging application may access a buddy list that may include various types of information regarding each of the buddy devices on the buddy list, including an on-line/off-line status indicator that displays whether each of the buddy devices is currently logged-in to the server. The device user may then utilize the messaging application to select a messaging buddy from among the listed buddy devices on the buddy list.
- The device user may utilize the messaging application to determine whether the selected messaging buddy is available to receive a video message from the user device by using any appropriate means. For example, the device user may simply view the foregoing on-line/off-line status indicators from the buddy list. If the selected messaging buddy is not currently available to receive a video message from the user device, then the device user may utilize the messaging application to create a new cache file in the cache to temporarily store the video message.
- The messaging application may also store various types of auxiliary message information into the cache file as part of the corresponding cached video message. For example, the foregoing auxiliary message information may include, but is not limited to, a video format for the video message and a storage location identifier for the video message. The device user may then utilize the messaging application to create and store the actual video message data into the corresponding cache file, and may log-off of the server when finished.
- Subsequently, the selected messaging buddy may utilize a corresponding buddy device to log-in to the server by providing various types of log-in information. The server may responsively send a message notification to the buddy device regarding the cached video message that has been saved into the cache by the user device. The foregoing message notification may include any previously-stored auxiliary message information including, but not limited to, a video format and a storage location identifier for the cached video message.
- The selected messaging buddy may then download the cached video message from the cache, and may subsequently view the downloaded video message on a display of the buddy device. After initially viewing the downloaded video message, the selected messaging buddy may determine whether to retain or delete the downloaded video message after it has been viewed, and may then finally instruct the buddy device to log-off of the server. The present invention therefore provides an improved methodology for performing caching procedures in an electronic network.
